Water
A weekly watering is usually sufficient for Ruby Rubbers, which retain moisture in their thicker leaves.
Yellowing and falling leaves can be a sign of overwatering, which can lead to root rot.
Lighting
Expose your Ruby Rubber to very early direct morning sunlight, followed by indirect light for the rest of the day.
The leaves of these indoor plants will give off a ruby glow when exposed to 8+ hours of filtered light each day.
Temperature & Humidity
The Ruby Rubber likes temperatures between 65-80°F. As tropical plants, they prefer a more humid environment — a pebble tray or humidifier can help fill the humidity gap!
